Bases: awslimitchecker.services.base._AwsService

• critical_threshold (int) – the default critical threshold, as an integer percentage, for any limits without a specifically-set threshold.
• profile_name (str) – The name of a profile in the cross-SDK shared credentials file for boto3 to retrieve AWS credentials from.
• account_id (str) – AWS Account ID (12-digit string, currently numeric) for the account to connect to (destination) via STS
• account_role (str) – the name of an IAM Role (in the destination account) to assume
• region (str) – AWS region name to connect to
• external_id (str) – (optional) the External ID string to use when assuming a role via STS.
• mfa_serial_number (str) – (optional) the MFA Serial Number string to use when assuming a role via STS.
• mfa_token (str) – (optional) the MFA Token string to use when assuming a role via STS.
